### Hip Hip Array!

We have been exploring arrays!

Row x Column = Product

The multiplication for the array above is
3 x 4 = 12
because it has 3 rows of 4.

When the factors are different digits,
the arrays are in the shape of a rectangle.
When the factors are the same digit,
the array is a square!
Here is a quiz.
Be sure your math sentence matches the picture!

Do you see any arrays at your house? Tell us about it!

1. Dear Mrs. Yollis,
I enjoyed your post about arrays!The fun part of arrays is finding them when you least expect them!
For example, taped next to me is a year calendar. It has 3 columns and 4 rows. There are 12 months shown in all.
Last year we went on an array hunt at our school and found all kinds of examples! I bet you can find some too!
Are you going to have an array finding contest?

2. Dear Mrs Yollis and class,

Great post about arrays. Like Mrs Hembree mentioned in you comment arrays are really every where.

I have a couple in my home for I have a column of 4 boxed square as a window and 5 rows going down.
Now I wonder if you know how many all together.

Somehow I feel you will all know the answer to my question.

3. @ Mrs.Yollis,

I’m Mikayla from 2KM (Mrs Morris class).

I like your blog post that you did about arrays. I enjoyed reading it with the class.

I like the video you made with the choses .I enjoyed working them out with my class at school and again at home.

We have lent about array at school to work out times tables.

I have lent my one’s, two’s, five’s and my ten’s. every one in my class have been leaning them as well Mrs Yollis’s class.

4. Dear Mrs Yollis and class,

Arrays can help us visualise numbers and how they can work. We can see arrays in some many places.

As an example, we may see a floor with a large number of tiles. We could count all tiles but if we know how many in a row and how many in a column, we can calculate to the total without needing to count each tile.

Hi I'm Blake from Techie Kids. I was thinking that I have arrays in my cupboard. That made me think of how many plates and cups I have.

I watched your video of how to leave a good comment. It helped me a lot. Thanks for sharing this video.

Sincerely,
Blake

6. Dear Mrs Yollis,

In Grade 3 we are learning about Decimals which are really easy to understand.

At home I do see some arrays for example the tiles in the Bathroom.

Another Excellent post.

We enjoyed the awesome video that your class created. The video helped our students understand arrays a little bit more than before. We will have our video of arrays posted to our blog Tuesday. Please check it out!
We explored our school yesterday and found a lot of arrays. Then we went home looking for things to bring in to create an array. It's amazing what you can use to create an array. :)

8. Great Post.

9. Dear Mrs. Yollis and class,

I love that you're learning about arrays. That was always one of my favorite things to teach about because there are so many examples around us! Just as I look around my house right now, I see a 7 x 5 array of bricks on my fire place. I also see a 14 x 2 array of DVD's on the bookshelf. I can't wait to hear what some of the examples are that you find in your home!

10. Dear Mrs Yollis,

great post I just love it so much!

11. Dear Mrs Yollis,

I love your post on arrays and I learned many things about them. I have an array two rows of three, which is our cook top in the kitchen. I also have an array that is outside in our garage which is wheels on a car. There are two rows of two.

12. Hello Mrs.Yollis,

13. Dear Mrs. Yollis and class,

My name is Mary LaCoste, and I am a student at the University of South Alabama currently taking EDM 310. Your class did a great job with this blog post about arrays. I guess I never realized how many of them are all around us. Math does surround us! This was great practice for multiplication as well. My third grade daughter and I watched your video, and we almost got all of them correct. We both thought it was a fun way to learn about arrays. Thanks for your post!
